我是python语言的新手，但我需要了解导致错误的原因＆＃34; AttributeError：＆＃39; OAndX＆＃39;对象没有属性＆＃39; run＆＃39;＆＃34;当我使用python3解释器来运行它时。感谢任何人都可以提供帮助。
答案 0 :(得分：1)
您应该将run方法放在您的OAndX类方法下，如下所示：
class OAndX:
def __init__(self):
# Initialize Pygame
pygame.init()
# Create the clock to manage the game loop
self.clock = time.Clock()
display.set_caption("Noughts and Crosses")
# Create a windows with a resolution of 640 x 480
self.displaySize=(640,480)
self.screen=display.set_mode(self.displaySize)
# will either be 0 or X
self.player="0"
def run(self):
while True:
# Our Game loop,Handle events
self.handleEvents()
# Draw our background and grid
self.background.draw(self. screen)
self.grid.draw(self.screen)
# Update our display
display.update()
# Limit the game to 10 fps
self.clock.tick(10)
